Efficient Gate-tunable light-emitting device made of defective boron nitride nanotubes: from ultraviolet to the visible
(Nature Publishing Group, 2013-09)
Boron nitride is a promising material for nanotechnology applications due to its two-dimensional graphene-like, insulating, and highly-resistant structure. Recently it has received a lot of attention as a substrate to grow ...
Long-lived oscillatory incoherent electron dynamics in molecules: trans-polyacetylene oligomers
(IOP Publishing, 2013-04)
We identify an intriguing feature of the electron-vibrational dynamics of molecular systems via a computational examination of trans-polyacetylene oligomers. Here, via the vibronic interactions, the decay of an electron ...
Ab initio molecular dynamics on the electronic Boltzmann equilibrium distribution
(IOP Publishing, 2010-08-31)
We prove that for a combined system of classical and quantum particles, it is possible to describe a dynamics for the classical particles that incorporates in a natural way the Boltzmann equilibrium population for the ...
Two-magnon bound state causes ultrafast thermally induced magnetisation switching
(Nature Publishing Group, 2013-11)
There has been much interest recently in the discovery of thermally induced magnetisation switching using femtosecond laser excitation, where a ferrimagnetic system can be switched deterministically without an applied ...
Network dynamics in nanofilled polymers
(Nature Publishing, 2016-04-25)
It is well accepted that adding nanoparticles (NPs) to polymer melts can result in significant property improvements. Here we focus on the causes of mechanical reinforcement and present rheological measurements on favourably ...
Poly(3,4-ethylenedioxythiophene) (PEDOT) Derivatives: Innovative Conductive Polymers for Bioelectronics
(MDPI, 2017-08)
Poly(3,4-ethylenedioxythiophene)s are the conducting polymers (CP) with the biggest prospects in the field of bioelectronics due to their combination of characteristics (conductivity, stability, transparency and ...
Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides
(Nature, 2019-07-29)
Chalcogen vacancies are generally considered to be the most common point defects in transition metal dichalcogenide (TMD) semiconductors because of their low formation energy in vacuum and their frequent observation in ...
Surface state tunable energy and mass renormalization from homothetic quantum dot arrays
(Royal Society of Chemistry, 2019-12-28)
Quantum dot arrays in the form of molecular nanoporous networks are renowned for modifying the electronic surface properties through quantum confinement. Here we show that, compared to the pristine surface state, the band ...
Time-Dependent Magnons from First Principles
(American Chemical Society, 2020-02)
We propose an efficient and non-perturbative scheme to compute magnetic excitations for extended systems employing the framework of time dependent density functional theory. Within our approach, we drive the system out of ...
One-dimensional flat bands in twisted bilayer germanium selenide
(Nature Publishing, 2020-02-28)
Experimental advances in the fabrication and characterization of few-layer materials stacked at a relative twist of small angle have recently shown the emergence of flat energy bands. As a consequence electron interactions ...
